Another in the astonishing series of science and nature films narrated by writer/naturalist John Kieran, The Heart achieves a surreal effect from the combination of aimless narration and precise German visuals. Like the other films in the "John Kieran's Kaleidoscope" series, it was reworked from a Thirties documentary produced in Germany and relicensed as "alien property" after the war. Without meaning to frighten, this film spreads feelings of unease.
With animation and X-ray motion radiography.
